OHD3-45M Application Field and Working Principle

The OHD3-45M is a mechanical thermostat, a type of temperature sensor that is commonly used to detect and control indoor environmental temperature. It is most commonly employed in residential and commercial buildings, such as in HVAC and commercial refrigeration systems. This type of thermostat is also commonly used to control engines and other automotive equipment.The OHD3-45M is a mechanical version of a thermostat, which means it utilizes a bi-metallic strip to measure and monitor temperature. When the temperature rises or falls, the bi-metallic strip will bend. This bending of the bi-metallic strip is used to control the opening and closing of the contacts within the thermostat, thereby setting the desired temperature. This motion of opening and closing the contacts is known as “switching” and is what the OHD3-45M thermostat is designed to do.The OHD3-45M is highly accurate and features a wide range of temperature adjustable settings, from -50 to 260 degrees Celsius (-58 to 500 degrees Fahrenheit). This high range of adjustability allows for precise temperature control, ensuring the OHD3-45M can meet the needs of virtually any application. The mechanical thermostat also features a safety device, which will cause the thermostat to shut off if the temperature exceeds the upper or lower limit of the temperature range. This safety feature helps ensure that the temperature does not get too hot or cold, potentially damaging the system or components within the system.The OHD3-45M thermostat is also easy to install and use, featuring simple wiring diagrams that allow for quick wiring of the thermostat. The flexible mounting bracket also ensures ease of installation and provides the user with the ability to mount the OHD3-45M in almost any place desired.Overall, the OHD3-45M thermostat is an excellent choice for users who are looking for a reliable and accurate mechanical thermostat to control temperature in their residential or commercial building, engine, or other automotive equipment. Its wide range of temperatures adjustable settings and ease of installation make it an ideal choice for anyone looking for a thermostat to meet their specific needs.
